The Lowdown

Alright crew, Rusty here. Let’s break down what this forecast is serving up, state-side.

We’re in a bit of a lull to start. The first real chance to wet a line doesn’t show up until Tuesday, September 8th. So you’ve got a few days of flat, messy, onshore junk to sit through.

The big highlight, and really the only one worth gettin’ your wetsuit for, is Tuesday the 8th of September at Kohala Lighthouse. We’ve got a solid 6ft to 5ft swell from the ENE runnin’ with a sweet 11-10 second period. That’s a proper groundswell with some punch to it. The combined swell energy is (880) dropping to (759), which is a decent pulse of power. The selling point here, though, is the wind. We’re talkin’ glassy conditions in the morning with a light westerly before it goes light north-northeast. That’s about as clean as a wave gets. Water temp is 27°, which is totally average for this time of year – no surprise cold-water shocks. Just remember, this is an advanced reef break that breaks consistently, and it can get crowded. The swell direction from the east-northeast is a perfect match for this spot. Mark that Tuesday in red.

Wednesday the 9th the swell fades a touch, and the wind cranks back up from the east, turning the lineup into lumpy, bumpy chop. Not good.

Way off in the distance, there’s a whisper of something on Sunday, September 20th. More than a week away, so take it with a grain of salt. We could see some cleaner conditions with a cross-offshore breeze and waves in the 4ft to 5ft range from the east. The energy is low at (243) to (190), but if the wind holds, it could be a fun little session.

Monday, September 21st is similar, with a bit more energy (325 to 361) and cleaner winds. For a second-week look, that might be your best bet.

The bottom line? If you want the best of the bunch, Tuesday the 8th of September at Kohala Lighthouse is your window. Chase the glass. After that, we’re waitin’ on a possible late-weekend clean-up way down the line.

Rusty.

Information about the Kohala Lighthouse Surf forecast

The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
